    Look at the underside of the leaves with a loupe. I think you have bugs, maybe mites. More info about you grow medium, pH, nutes, etc.

    make pH correction unnecessary

      No no bugs I use super soil and roots organic soil mix but I didn’t have a lot of my super soil left so I mixed my last gro we medium in with what I had left over and new roots organic soil mixed with it the plant was doing wonderful and yesterday night I looked at her and she had rust spots on her lower leaves and 2 nights before I added cal-Meg to her feeding cuz I haven’t added anything but plain water until then so I’m wondering if by me adding the cal-Meg might have done something to her

      I don’t use any nutrients only what is in my super soil from nature’s super soil compost and mix it in with my roots organic I haven’t had to check my run off my last grow was on point for the most part no deficiency or anything I guess I need to check my run off

      In soil, you ought to see pH from about 6.2 to 6.8. If it gets too acidic, that kills off all the beneficial microbes which inhibits nutrient uptake.

          If you are using super soil or with any soil you don’t have to check ph as long as you have a well balanced soil. You may need to re amend your soil. Add gypsum and that should take care of that issue if it is a cal mag issue, don’t flush your soil by doing that you are depleting it from nutrients then you will definitely have to top dress. I use malted barley it’s full of enzymes and that help kick start the microbial life in the top 2-3 inches of your soil which should Never dry out.

            Ok well my ph is 6.3 run off and my ppm is at 766

          How much molasses do you use and how often? That lowers your pH. I hope you didn't flush yet. Did you look at Weed Pharma's Stonington Blend latest post? It might help you.
